Tank Manufacturing and Industrial Services in California

California’s economy — the largest in the western United States — drives demand for steel storage tanks across nearly every industry MMI serves: municipal water and wastewater, oil and gas production (San Joaquin Valley, Los Angeles Basin), agriculture (Central Valley), food and beverage processing, mining, and industrial manufacturing.

MMI Tank is a licensed California contractor providing bolted and field-welded steel tank engineering, fabrication, and erection throughout the state. Our Phoenix fabrication plant is one day’s freight from most California job sites, and our field crews regularly work in California’s unique regulatory and seismic environment.

California-Specific Capabilities

Seismic Design

California’s seismic requirements are among the most stringent in the country. Every MMI tank installed in California is designed with full seismic analysis — API 650 Appendix E for petroleum and industrial tanks, ASCE 7 referenced through AWWA D100/D103 for water tanks. Our engineers are experienced with California Building Code (CBC) seismic provisions and site-specific geotechnical conditions.

California Environmental Compliance

  • SWRCB (State Water Resources Control Board) — drinking water tank permits and approvals
  • CalGEM (formerly DOGGR) — oil and gas production facility tank requirements
  • CARB (California Air Resources Board) — vapor recovery and floating roof requirements for volatile liquid storage
  • DTSC / CalEPA — hazardous material storage tank regulations
  • CEQA — environmental review support for tank construction projects

Industries Served in California

  • Water and wastewater — municipal utilities, special districts, and private water systems from San Diego to Shasta County
  • Oil and gas — San Joaquin Valley production, LA Basin, and coastal operations
  • Agriculture — Central Valley irrigation, dairy, wineries, and food processing
  • Food and beverage — Napa/Sonoma wineries, Central Valley processors, Southern California manufacturing
  • Mining — aggregate, mineral, and industrial mineral operations
  • Municipal — cities, counties, and water agencies throughout California
  • Fire protection — wildfire and structural fire water storage in high-risk zones

Freight and Logistics Advantage

MMI’s Phoenix plant is approximately 370 miles from Los Angeles and 660 miles from San Francisco. Bolted tank panels and shop-fabricated components reach most California sites within one business day of shipment — faster than Gulf Coast or Midwest fabricators and with significantly lower freight costs.
